Drinking alcohol

Options

A. Stimulates muscle activity
B. Speeds up impulse transfer
C. Impairs coordination of different body parts
D. Makes the driver extra careful

Answer

**Step-by-Step Text Solution:**

1. **Understanding Alcohol's Effects on the Body:**
- Alcohol is known to have various effects on the body, particularly on the brain and motor functions.

2. **Impact on Muscle Coordination:**
- One of the primary effects of alcohol consumption is the impairment of muscle coordination. This is primarily due to its impact on the cerebellum, the part of the brain responsible for coordinating voluntary movements.

3. **Speech Impairment:**
- As coordination is affected, speech can also become incoherent. This is a direct result of the loss of muscle control, which affects the muscles involved in speech.

4. **Alcohol as a Depressant:**
- Alcohol acts as a depressant, meaning it slows down the central nervous system. This leads to dulling of the senses and a decrease in overall body function.

5. **Evaluating the Options:**
- **Option A:** "It stimulates muscle activity" - This is incorrect because alcohol actually impairs muscle coordination.
- **Option B:** "It speeds up impulse transfer" - This is also incorrect; alcohol can lead to disorders like Neuritis, which involves inflammation of axons and slows down nerve impulses.
- **Option C:** "It impairs coordination of different body parts" - This is correct, as discussed earlier.
- **Option D:** "It makes a driver extra careful" - This is incorrect; alcohol typically makes drivers less careful and increases the risk of accidents.

6. **Conclusion:**
- Based on the evaluation of the options, the correct answer is **Option C: It impairs coordination of different body parts.**
